DEvioE FOR MAKING FREE-HAND RELIEF DECORATIONS.

srncrrrcntrron forming part of Letters Patent No. 634,786, dated Octoberin, 1899. Application filed March 23, 1899. Serial No. 710,234. (Nomodehl T0 at Ll/horn it may concern:

- Beitknown thatLWILBERTA.WILL0WER,

declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

.Apparatus as heretofore generally constructed for freehand relief-workin decoratin g Walls and ceilings by laying on strips, fillets, orribbons of plastic material are not easy of management and control andgreat diflicnlty has been experienced in obtaining a uniform feed of thematerial.

The present invention is designed to provide an apparatus of thecharacter aforesaid possessing the following advantages: capable ofbeing easily handled, manipulated, and cleaned; enabling a steady anduniform flow of the material; providing for a quick refilling of the canor receptacle; enabling ,both hands being used to grasp the can anddirect itsmovements 5' have the parts readilyaccessible for inspection,cleaning, and the making of repairs, and which will involve a sim: pleconstructionv and produce satisfactory results.

With these and such other ends as may result from the specialconstruction of the apparatus, the, invention consists of the novelformation and combinations of the parts, which hereinafter-Will be morefully described, illustrated, and claimed.

The size and capacity of the apparatus may be varied and the nozzlereplaced by another of different form to suit the nature andrequirements of the work, and such other changes in the form,proportion, and minor details of construction may be resorted to inadapting the invention to special needs with out departing from orsacrificing any of its advantages.

In the drawings, Figure 1 isa detail, View showing the invention inoperation. Fig. 2 is a vertical central section;

tail view of a different form of nozzle.

Corresponding and like parts are referred to in the followingdescription and indicated with the teeth 14; of the rod 5.

Fig. 3 is a dein all the views of the drawings by the same referencecharacters.

' The. vessel-or receptacle 1 is preferably of cylindrical form and isopen at its upper end and closed at its lower or delivery end, thelatter being provided with a screw-threaded collar for detachableconnection therewith of a nozzle 3. The collar 2 is. of' conical form,and by having the nozzle 3 detachably connected therewith a nozzle ofrequired sizeand form may be placed in position, and when it is requiredto refill the vessel the nozzle can be detachedand the collar 2 dippedinto the batter or material employed in the decorative Work. A cross-bari is removably fitted to the open end of the receptacle 1 and iscentrally apertured for the passage therethrough of the rod 5, carryingat its inner end a piston 6, by'lneans of which the composition isforcibly expelled through the nozzle 3. The

cross bar or support 4 is secured to the receptacle at its ends in anyconvenient and substantial manner, and, as shown, it is provided.

With plates 7, hinged thereto and apertured or slotted to engage withears, stops, or lateral extensions 8, projecting from the sides of the Abracket-lug 10 is formed with the cross-bar near one end, and an arm 11is pivoted thereto and carries a pawl or dog 12, by means of whicnthepiston is advanced as required to secure a proper delivery of theplastic composition. A spring 18 is attached at one end to the arm 11,and its free end braces the dog 12 and holds its active. end inengagement This spring can be turned aside upon its fastening, so as topermit the dog 12 to fall away from the teeth 14:, thereby enabling therod to be freely withdrawn at any time.

The piston is composed of a back plate 15,

a clamp-plate 16, and an intermediate pack- 1 ing 17 of leather, rubber,or like flexible material commonly employed in devices of this nature.The packing 17 is clamped between the plates 15 and 16 and is held inplace by bolts'or fastenings 18 passing through corresponding openingsin the several parts. The lowerend of the rod 5 is threaded and makesscrew-thread connection with the piston,

whereby the latter can be readily disconnected,

rod 5 and bracket-lug 10 are received in the space formed between thebifurcations. The outer orfree endofthepivotedarmis normally heldoutward from the cross bar or support 4: by means of a suitably-arrangedspring. As illustrated, the spring 20 is formed of a single length ofWire doubled upon itself and curved longitudinally, the outer end of thespring being bent to form a loop or eye 21, which embraces the arm 11,and the inner or opposite end of the spring-wire beingsecured by anyform of fastening means to a side of the receptacle. The inner or lowerportion of the spring spans the adjacent pivoted plate '7 and obtains abearing against the side of the receptacle 1, to which it is secured inany substantial manner. Obviously the spring may be secured to the sideof the receptacle or a convenient portion of the support 4 when foundadvantageous and if preferred. The construction illustrated isdesirable, as it admits of the piston, the support 4 and adjunctiveparts being readily disconnected from the receptacle for any desiredpurpose.

In practice the pivoted arm 11 is oscillated in. order to advance thepiston step by step in order to expel the material as the work ofdecorating progresses. Any convenient means may be employed forimparting movement to the arm. As disclosed, a bar 23 is pivotallyconnected at its outer end to the extremity of the arm 11, and its-inneror lower end is eX- panded and provided with a finger or thumbrest :24.This bar extends along the side of the receptacle 1 a sufficientdistance to enable the rest 24 to be conveniently reached by the thumbor finger and yet allow the hand to firmly grasp the receptacle anddirect it over the surface to be embellished or deco: rated.

The composition, which may be a batter of plaster-of-paris of the properconsistency,is supplied to the receptacle 1 either by removing thepiston and filling the batter to the vessel through its upper end or bydipping the lower end of the vessel into the batter and withdrawing thepiston previously forced into the receptacle to the limit of its inwardmove ment. When the piston is utilized for charging the apparatus, thespring 13 is turned aside so as to permit the dog 12 to fall away fromthe ratchet-teeth 14. After the apparatus has been charged and therequired nozzle placed in position the receptacle is grasped by bothhands, about as shown in Fig. 1 of the drawings, the thumb engaging withthe rest 24. An oscillation of the pivoted arm 11 depresses the pistonand forcibly ejects the material through the nozzle 3 in a strip,ribbon, or fillet, according to the size and shape of the said nozzle.As the material emerges from the nozzle it is laid on the surface to bedecorated by properly manipulating and directing the apparatusover thesurface, as experience will dictate and as well understood in the art.

Having thus described the invention, what is claimed as new is 1. Inapparatus of the character described, a receptacle having adischarge-nozzle, a centrally-apertured support, and means fordetachably connecting the said support with the receptacle, incombination with a piston carried by said support and directed in itsmovements thereby and adapted to expel the material from the receptacle,and actuating means applied directly to the aforesaid support andmovable therewith and adapted to advance the piston to its work,substantially as described.

2. In apparatus of the nature described, a receptacle provided with adischarge-nozzle, a centrally-apertured support, means for detachablyconnecting the support with the receptacle, a piston carried by the saidsupport and directed in its movements thereby and having a handle at theouter end of its rod, a vibrating arm pivoted to the support andcarrying a dog to engage with the piston-rod, and a spring for holdingthe vibrating arm in a normal position to advance the piston to itswork, substantially as set forth.

3. In apparatus of the nature specified, a receptacle, a pistonoperating in the receptacle, a pivoted arm provided with operating meansfor actuating the piston, and an operating-rod applied to the pivotedarm and extending along the side of the receptacle and provided at itsinner end with a rest for the thumb or finger of the hand to obtain apur- IIO chase upon when the apparatus is in opera Zle, a piston, avibratory arm provided with means for actuating the piston, and a springhaving an end portion placed against the side of the receptacle andhaving its opposite end portion extending over the receptacle andembracing the outer end portion of the operating-arm, substantially asdescribed,

of the receptacle and centrally apertured and provided with abracket-lug, a piston having its rod operating through the opening ofthe support and provided along its length with a series of teeth,an armpivoted to the bracketlug and embracing the sides of the piston-rod, aspring-actuated dog applied to the pivoted arm and adapted to cooperatewith the teeth of the piston-rod, a spring for returning the pivoted armto a normal position, and an operating-rod having connection with thepiv oted arms and provided at its inner end with a rest, the parts beingcombined and arranged to operate substantially in the manner and for thepurpose specified.

In testimony whereof I affix my signature inpresence of two witnesses.
